So? Science Fair? Variables? Review of Literature?
Mmmk.
So my project is:
Which percent of worm castings versus store brought soil will make bean plants grow faster?
And I add more worm castings as I go.
Ex. 100% soil 0% worm castings, 25% worm castings 75% soil, 50% worm castings 50% soil, etc.
I know what my independent variable is; it’s what I change so it would have to be the WORM CASTINGS.
But what is my dependent variable?
And what the hell is a Review of Literature?
And how do I write it?
HELP ME PLEASE!!!
Thanksss.

A literature review is a listing of all experiments that bear on yours. They may have used coir on bean plants as the variable or they might have tried maize instead of beans in worm castings. You need to look up papers on this type of experiment.

Your dependent is what responds to the changes you make. An experiment asks a question. The dependents answer it.
